Sabina, due to its history and morphology, is rich of medieval towns still intact, built on top of the hills and dominated by fortresses and castles.

The imposing Castle of Roccasinibalda is the most significant example of military architecture in (Upper) Sabina, for its dimensions and for its good conditions. The whole village is still shaped as a fortified hamlet by the typical medieval system. The fascination of this place encouraged throughout the centuries the belief in strange voices and mysterious apparitions.

Another magnificent castle, recently restored to its ancient beauty, is located in Collalto Sabino. In the XVII century when owned by the noble Roman family Barberini, the castle has been enriched with precious marbles, mosaics, paintings and stems representing golden bees, symbol of the family. All this was destroyed throughout the centuries.

The Castle of Rocchettine (XIII century) was abandoned by its inhabitants fifty years ago and represents one of the most characteristic sights in (Lower) Sabina. The castle is surrounded by a green landscape and is separated from the village of Rocchette by a gorge shaped by the “l'Aia” stream.

A pentagonal tower, over twenty meters high, dominates the ruins of the Castle of Catino (X century), built by a rocky slope.
